It's unclear why would need an account in order to interact with other users?
This isn't Reddit or 4chan, this is a site where views and opinions are being exchanged. User accounts have been a way to monitor interactions and store data relative to a certain person almost since the Internet was created.
edit: TwoSides is for constructed, meaningful interactions, from what I've gathered. Reddit is pretty great but far from what TwoSides can achieve.
